Abstract
In this study, using the flexible material of PDMS to fabricate the lenticular lens with imprinting process, and combining the lenticular lens and interlaced images to make our both eyes see the different images separately by means of the optical properties of lenticular lens which produces the three dimensional stereoscopic images. The experimental results in aspect of different parameters of images demonstrated that the more number of images of taking photos, seeing the stereoscopic images in different angle is more smoother; and with increase of the optical angle, the stereoscopic effect is more better. In the aspect of different lenticular lens, the results showed that the smaller pitch of the lenticular lens, the higher resolution of stereoscopic images; and when the curvature radius of the lenticular lens increases, it can be seen the deepest stereoscopic thickness in the same optical angle in smaller Stereoscopic angle, which indicates that the stereoscopic depth sensing is more obvious. And it is a method defined to determine the quality of the effect of the stereoscopic images. Finally, the lenticular lens were placed on the different radius of curved surface using the flexible property of PDMS, and the experimental results showed that with the decrease of the radius of curved surface, the curvature radius and pitch of the lenticular lens will increase, causing the stereoscopic images to produce obvious phenomenon of distortion. However, by modification of images and lenticular lens , it can be showed the better image quality and stereoscopic effect on the curved surface. And comparing to the flat and the curved stereoscopic images using the index of Stereoscopic angle to determine the quality of stereoscopic effect, the results showed that the Stereoscopic angle of the curved stereoscopic images are smaller than flat ones; namely, the stereoscopic effect of curved stereoscopic images are more obvious.
